Many budget smartphone users are wondering about the functionality of their devices, especially when it comes to modern contactless technologies. Owners of the popular Xiaomi Redmi 8 model often look for information about whether you can pay for purchases in stores with a touch of the phone to the terminal, which is quite logical interest, given the ubiquity of fast payment systems.
But there is confusion when looking at specifications: some sources mention NFC support, others say it’s completely absent, and the reality is that the global version of the device, which has been officially shipped to most countries, including Russia and the CIS, doesn’t have an NFC module.
However, there are regional modifications and Chinese versions where the situation may be different, which gives rise to many myths. In this article, we will discuss in detail how contactless communication in Redmi 8, how to check for a chip yourself, and what alternative solutions exist for those who want to use a smartphone for transactions.
Technical features of the NFC module in the Redmi line
NFC (Near Field Communication) is a short-range wireless standard. In Xiaomi smartphones, this module is usually located at the top of the body, next to the main camera. The technology requires not only software support in the operating system, but also a physical antenna built into the motherboard.
In the case of the Redmi 8, released in 2019, Xiaomi decided to optimize the cost of the device, which led to the fact that in the global versions (Global Version) the physical NFC chip was excluded from the specification. However, in the Chinese version of the smartphone, known as Redmi 8 China, this module was present.
⚠️ Note: If you are buying a used device or ordering it from abroad, be sure to specify the region of origin (Global or Global). CN), As the contactless payment function will depend on this.
The absence of a module in the global version does not mean that the MIUI operating system does not have the appropriate settings. The menu can display options, but without the hardware they will remain inactive.
How to check for NFC in your Xiaomi Redmi 8
Before you try to set up payment or file transfer, you need to make sure that you have the hardware. There are several ways to do diagnostics that do not require the installation of third-party software and give an accurate result.
The easiest way is to search in the system settings, open the settings menu and use the search bar at the top of the screen, type in "NFC." If the module is physically present and the drivers are working correctly, the system will give the corresponding menu item to turn the function on or off.
If you don't find anything, you can use an engineering menu or codes. Type ##6484## in the phone book. The CIT menu will open, which will show you the complete list of test components of the device. Find the "NFC" item in the list and click on it to run the test.
☑️ Diagnostics of the communication module
Also worth paying attention to the packaging of the device: On the back of the box, where the specifications are printed, the NFC logo or corresponding inscription is often indicated, if the module is provided by the manufacturer for a particular batch.
Why Redmi 8 doesn’t have NFC: Manufacturer’s Decision Analysis
The decision to remove the short-range module from the global version of Redmi 8 was dictated by fierce competition in the budget segment, engineers had to meet a certain price category, sacrificing some features to improve other parameters that are more noticeable to the mass user.
The main focus of this model was on battery autonomy and capacity, the device received a battery capacity of 5000 mAh, which was a remarkable figure at the time, and the Quick Charge 3.0 fast charging technology was introduced, which required appropriate power controllers.
- 📉 Cost of components: Module NFC and associated antenna group increase the cost of the device, which is critical for public sector.
- 🔋 Energy consumption: Although NFC consumes little energy in sleep mode, its presence requires space inside a compact housing.
- 📡 Priorities: Resources were redistributed to improve cellular reception and the quality of the main speaker.
So the lack of NFC was a compromise that allowed users to offer a large screen, a capacious battery and a fresh version of Android at a very aggressive price, which for many users was profitable, because contactless payment is not used by everyone.
💡
If it's critical NFC, But you already bought the Redmi 8 without it, consider using it. NFC-tags or rings that can be worn separately, although less convenient.
Alternative methods of payment and data transfer
Even if your Xiaomi Redmi 8 doesn’t have a native NFC module, it doesn’t mean you can’t use modern digital services, but there are workarounds and alternative technologies that allow you to solve similar tasks.
You can successfully use Bluetooth technology or cloud services to transfer files and contacts. MIUI has a built-in "Mi Drop" feature (now known as ShareMe), which allows you to transfer files at high speed over Wi-Fi Direct. This is even faster than classic NFC, although it requires pre-pairing.
For purchases in stores where the terminals do not support contactless, there are always traditional methods.
- 💳 Plastic cards: Classic card or smartphone payment via magnetic strip reader (if the terminal is old).
- 📱 QR-Codes: Many banking applications allow you to generate QR-payment code read by the cashier or terminal.
- ⌚ Smartwatches: If you have a smartwatch with NFC, You can tie the card to them and pay for purchases using your phone only to manage.
Some users are trying to use external NFC-readers connected through the connector USB Type-C, however, requires support. OTG and special drivers, and also do not allow emulating cards for payment, but only to read information from tags.
Comparison of Features: Redmi 8 with and without NFC
To better understand the difference between the two, let’s look at a comparison table that will help you identify which version of the device you’re holding based on indirect features, as they may look identical.
| Characteristics | Redmi 8 Global | Redmi 8 China (CN) | Redmi 8A |
|---|---|---|---|
| NFC module | Absent. | Present. | Absent. |
| Support for OTG | There is. | There is. | There is. |
| Hall's sensor. | No (usually) | There is. | No. |
| Firmware region | Global / EEA / RU | China / MIUI CN | Global |
As you can see from the table, NFC is often correlated with the region of release. Chinese versions tend to be richer technically, but may have limitations in working with LTE frequencies used in other countries, and the lack of pre-installed services Google.
⚠️ Warning: Installing global firmware on the Chinese version of Redmi 8 (or vice versa) may cause the module to fail NFC, Even if it is physically present, due to differences in the drivers and calibration of the antenna.
Possibility of installation NFC-module and risks of modification
There are suggestions online that you can install the NFC module on your own in smartphones that don't have it, and in theory, if you have a motherboard that has a contact area for soldering the antenna and chip, it's technically possible, but for the Redmi 8, it's a very risky procedure and not recommended.
First, you need to find a compatible donor module that fits the size and connector. Second, you need professional soldering equipment and a deep knowledge of circuitry, and even after a successful physical installation, you need to flash the device and embed the appropriate drivers and edits in the system files build.prop.
Technical details of modification
Independent intervention in the hardware part of the device:
- 🚫 Deprives warranty: Any traces of opening and soldering will void warranty obligations.
- 🔥 Damage risk: There is a high probability of damaging the motherboard, which will result in the phone being completely inoperable.
- 📉 Instability: Even the installed module may not work properly, drain the battery or conflict with other components.
Given the low cost of the smartphone itself, the economic feasibility of such a modification tends to zero. It is easier to purchase a mid-range model where NFC is present initially, for example, the Redmi Note series or Xiaomi Mi.
💡
The attempt to sell NFC into Redmi 8 is a complex technical experiment with a high risk of turning the phone into a brick, which does not guarantee the result.
